Scientists researching reefs off Australia exposed the fact during Thursday that sharks play a crucial role in the health of coral at the same time overfishing of them made reefs more critical to global warming as well weather calamitous event.  A research team, headed by Dr Mark Meekan from the Australian Institute of Marine Science (AIMS), researched the impact of sharks at the Rowley Shoals and Scott Reefs, 300km off north-west Australia beyond 10 years.

He explained that where shark numbers are declined they see a crucial transformation in the structure of food chains on reefs. They view expanding numbers of mid-level predators such as snappers, and a decrease in the numbers of herbivores such as parrot fishes.

That's absolutely worrisome as far as the transformation in environmental factor is concerned because that's hat is leading us towards global warming.
